摘要： The invention includes at least two free disks arranged between a drive-torque transmission disk and an output-torque receiving disk, each of the at least two free disks being freely rotatable. When a torque is to be transmitted, mutual gaps between the drive-torque transmission disk, the at least two free disks and the output-torque receiving disk are narrowed, so that the input torque of the driving unit is transmitted from the drive-torque transmission disk to one free disk adjacent to the drive-torque transmission disk by friction, the torque transmitted to the one free disk is transmitted to another free disk adjacent to the one free disk by friction, and the torque transmitted to the or another free disk on the most output-shaft side is transmitted to the output-torque receiving disk by friction.

摘要： A roller ski gear (300) wherein elastic wheels (302) are rotatably mounted on the front and rear portions of a boot resting plate (301), the elastic wheels each having a wheel supporting means having a circular rim portion formed on the outer periphery thereof and a tire portion mounted on a circular rim portion of the wheel supporting means and capable of being deformed in a direction normal to the running direction of the wheel. In the elastic wheel (302), it is possible to easily change the running direction with the axles of the wheels being maintained in the same direction, and by making use of this characteristic it is possible to operate the roller ski gear in the same way as operating a snow ski.
